About this 3D model

Hi everyone. My first post. I bought a 3D printer last week and the first thing I had to make was a knife. I cannot say this is finished, there still are parts need to be modified. However with some drilling and sanding, it is a fully functional model. I put up youtube video, so check out how it works. It's pretty cool. youtu.be/pWa41ig3-Rg
